The Lowdown
Alright, folks, Rusty here. Let’s be straight with you. I’ve looked over the forecast for our local patch, and I gotta say, it’s a tough one.
We’re staring down a 16-day window here, and honestly, there’s not a single day where the surf is good enough to get excited about. Not one. Every single session in the forecast is flagged as poor surf conditions. We’re looking at a full two-week-plus gap with no real recommendations. The first three days of September are off the table, and the pattern just doesn’t let up.
Let’s break it down. The best we see is a little bump of energy on Sunday the 6th, with a combined swell energy of 151 (moderate), coming from the ENE at 4 ft. The wind is a clean offshore from the NNE, but that swell period is a short 7 seconds. It’s a beach break setup, so it’s going to be a bit of a washout. The glassy conditions on the 6th afternoon at 3 ft ENE are nice, but the swell is just too weak.
On Thursday the 9th, the wind picks up from the S at 16 mph, and the swell jumps to 5 ft from the S with a period of just 5 seconds. That’s a messy, choppy onshore mess. With that kind of wind and a beach break, this setup is honestly more interesting for kite surfing than paddle surfing.
The water temperature is sitting at 65°, about 3° warmer than normal for this time of year. That’s a touch warmer than average, but it doesn’t help the waves.
Basically, the whole forecast is a dud. Kennebunk Beach is a sheltered spot, and it’s just not catching anything worthwhile. We’ve got a long stretch of nothing here. It’s a blank run, but for this area, that’s not too unusual. Forecasts can always change, but for now, don’t bother waxing up.
Rusty.

A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
